CanvasZoomPanDragLib 2.0.0

In Xaml: <cvLib:BorderZoomPanDrag Grid.Row="1" BorderThickness="1" BorderBrush="Black" ClipToBounds="True"> <Canvas Background="White" Width="350" Height="350" x:Name="cv" > </Canvas> </cvLib:BorderZoomPanDrag>

In Code-behind:

• Init canvas manager:

  CanvasManager canvasManager = new CanvasManager(cv, new Point3D(), new Point3D(10000, 10000, 0));

• Init drawing (Drawing/SelectableDrawing/DraggableDrawing):

  Selectable sel = new Selectable(new List<Point3D> { new Point3D(0, 0, 0) }, canvasManager);

  class Selectable : SelectableDrawingBase { public Selectable(IList<Point3D> pDecart, CanvasManager canvasManager) : base(pDecart, canvasManager) { }

  protected override List<Shape> CreateShapesOnCanvas()
  {
  	var shapes = new List<Shape>();
  	var el = new Ellipse();
  	var pCanvas = BasePointsCanvas[0];
  	Canvas.SetLeft(el, pCanvas.X - 10 / 2);
  	Canvas.SetTop(el, pCanvas.Y - 10 / 2);
  	el.Height = 10;
  	el.Width = 10;
  	el.Fill = COLOR_DEFAULT;
  	shapes.Add(el);
  	return shapes;
  }
  

  }

• Draw:

  canvasManager.Add(sel);
